SPECIFICATION forming part of Letters Patent No. 776,271, dated November29, 1904.

Application filed November 6, 1903. Serial No. 180,115. (No model.) 7

To all whom it may concern:

Be it known that I, FREDERICK THOMASSON, a subject of the King of GreatBritain and Ireland, residing at 47 Cleveland road, Higher Crumpsall,Manchester, in the county of Lancaster, England, have invented a new andusefulImproved Knotter, of which the following is a specification.

The object of this invention is to provide a simple form of knotter toenablewinders and ot ers to readily and speedily knot two ends of threador the like together.

The manner in which my said invention is to be performed or carried intopractical effect will be readily understood on reference to the sheet ofdrawings, in which Figure 1 is a front view of a simple form of myknotter. Fig. 2 is a front view of a knotter with an attached handle.Fig. 3 is a side elevation of Fig. 2. Fig. 4 is a view showing theposition of thread when forming the knot. Fig. 45 is aview showing theknot formed and slipped off the knotter in position for the loose endsto be severed, and Fig. 5 is a View of a modification.

For the purposes of my invention I take a piece of steel or othersuitable wire a of a convenient length and I bend or double the sameinto an inverted-U form somewhat likea hairpin, as shown at Fig. 1 onthe drawings. I then tile or otherwise form the inner side of the bendor loop at 7) to a cutting edge. The legs of the inverted U may be bentor formed in any suitable way for convenience of handling; but I preferto bend the ends inward and attach the wooden handle 0, as shown inFigs. 2 and 3. The sides of the handle are grooved to receive the wire,which is secured to the handle 0 by means of ametal ferrule d.

The person using this improved knotter holds the same in one hand and inthe other takes the two ends together, then passes the two pieces ofyarn around the legs of the U in a coil and draws the extreme endsthrough the space between the coil and the cutting edge of the loop, asshown at Fig. 4, then slips the coil upward off the ends of the loop andlegs, so as to form a knot, and gives a sudden pull at the two piecestogether, whereby the knot is pulled tight and the short projecting endsare cut off. These short ends may readily be removed by the thumb andfinger.

Fig. 5 shows a modification in which only one leg or member a of theU-shaped wire carries the cutting edge 6. A handle 0 with bands (Z (Zserves to hold the two legs a a together. One of the legs a is curvedand sharpened to form the cutting edge 6. The other leg is adjacent tothe cutting edge, but its only function is to assist in forming theknot.

I claim as my invention- 1. An improved knotter having two wire membersaround which a knot may be prepared, and a curved part at the end ofsuch members, the inner edge of said curved part being sharpened forcutting the knotted threads after the knot is slipped off said members.

2. An improved knotter of inverted-U shape having a cutting edge in theloop of the U, substantially as described.

3. An improved knotter, comprising a bandle, two wire legs extendingtherefrom and terminating in a loop, said loop having a cutting edge,substantially as described.

4. An improved knotter made from a single piece of steel wire bent orlooped in the form of a hair-pin, the inner edge of the loop beingsharpened for cutting the knotted threads, after the knot is slipped offthe said loop.

5. An improved knotter formed from a single piece of steel wire bent inthe form of a hair-pin and formed with an internal cutting edgesubstantially as described, and fitted with a handle for convenience ofcarriage and use.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FREDERICK TH OMASSON.
